Overview
  • Air Emission and Monitoring
  • Project Specifics
  • Careers

3
How Electricity Is Made
4
CEM in General Terms
  • Continuous Emissions Monitoring (CEM)
  • Sample the Flue Gas - One of Two Ways
  • Measure Directly at the Stack or Duct
  • Extract Sample and Transport to Analyzing
    Equipment
  • Log Results Electronically
  • Store Data for Historical Record

5
What Drives Improvement?
  • We Energies Emission Controls Influenced by
    Environmental Commitment and Governmental
    Regulations
  • EPA Clean Air Act 1963/1970/1990
  • Consent Decree 2003
  • Performance Specification 11 (PS-11) 2004
  • Clean Air Mercury Rule (CAMR) 2005

6
Clean Air Act
  • EPA Clean Air Act 1963/1970/1990
  • Sets Limits on Air Pollutants
  • Approves Plans for Reducing Air Pollutants
  • Assists in Supporting Clean Air Progress

7
Consent Decree
  • Agreement to Significantly Reduce Air Emissions
    From Coal-Fueled Plants
  • Nitrogen Oxide (NOX)
  • Sulfur Dioxide (SO2)
  • Particulate Matter (PM)
  • Mercury (Hg) which was optional

8
PS-11 and CAMR
  • Finalized Specifications and Test Procedures for
    Particulate Matter Continuous Emission Monitoring
    Systems (PM CEMS) at Stationary Sources
  • Finalized Clean Air Mercury Rule (CAMR) and
    Specification and Test Methods for Total Vapor
    Phase Mercury CEMS in Stationary Sources

P-5B Particulate Monitor
  • Probe and Analyzer Are Integral, One Unit
  • Measures at the Duct
  • Monitor Made to Withstand Outside Environment

BetaGuard Particulate Monitor
  • Probe and Analyzer Not Integral
  • Analyzer Housed in Equipment Shelter
  • Probe at the Stack
  • Gas Sample Transported Via Sample Line
